Check Digit Verification of cas no

The CAS Registry Mumber 51087-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,8 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51087-69:
(7*5)+(6*1)+(5*0)+(4*8)+(3*7)+(2*6)+(1*9)=115
115 % 10 = 5
So 51087-69-5 is a valid CAS Registry Number.

New synthesis and biologically active molecular design of deazapteridine-steroid hybrid compounds

Nagamatsu, Tomohisa,Yamada, Hiroki,Shiromoto, Kazuyuki

, p. 9 - 16 (2007/10/03)

This paper describes a facile and general synthesis of a new class of the hybrid compounds (4, 5 and 16), possessing 5-deazapteridine and steroid in the same ring system, by condensation of 6-(monosubstituted amino)uracils (9) or 6-(monosubstituted amino)-2-phenylpyrimidin-4(3H)-ones (14) with 2-hydroxymethyleneandrostanolone (10) or 2-hydroxymethylenetestosterone (15) under heating in the presence of p-toluenesulfonic acid monohydrate and their potential unti-coccidiosis activities.
